' cameraman-m PLUMMER, or cnE'srEa-1owa mmm a Be it known that I, CHARLES QHPLUMMER, a citizen of the United States ,view, the invention consists in .the details of America. and resident of Chestenrin-the" *county of Howard and State of Iowa, have invented certain new and useful Improve-i, ments in Cream-Ripeners, of which the-[following is a specification; I 1 This invention relates to cream ripener's and-particularly to means for-controlling the temperature of the cream and for agitat.-;

ing the same An object of this invention is to provide novel means for circulating the heating or cooling medium through the cream. contained in a vat, novel means being provided for permitting the circulation of the heat interchanging medium, novel means being furthermore provided for agitating or moving the said heat interchanging fmediumvertically of the vat in order that'the temperature of-the cream throughout.

may be uniform A still further object of this invention is to provide novelvmeans for rotating the heat interchanging medium, means being also provided for elevating or lowering the heat interchanging medium without'interrupting its rotary movement.

WVith the foregoing and other objects in of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

' In describing the invention in detaihreference will be had to the accompanying,

drawings forming part of this specification wherein like characters denote correspond g .the several "views, and. in

of coacting it or the said water may be subjectedtlo the action of heat for the purpose .of raising the temperature, the function of the tank being to supplycool liquid to the heat interchanging pipes in hot weather and p fi iqn etters fatenti Patented Aug} 2'7, 1912.

v I warm water to the heat interchanging pipes Grim/Inger,

in cool weather in order that the cream within the vet may be kept'at the proper temperature to insure itsripeningunder the best possible 'c'onditionsz'.

The vat is provided on. its exterior with at the; opposite end, which bearings are for the purpose of rotatably; holding the shafts B and 9 respectively. The shaft 8 has a bearings 6', 6, at one end and hearings 7, 7,

screw 'lOon its upper end, whereas the shaft 9 has a screw 11 on its upper end. The lower ends'of the'sh-afts 8 and 9 have gear wheels {12 and 13 respectively which are driven by a shaft- 14-having gear wheels 15 and 16 respectively, meshing with the gear wheels 12 and' lg; v v v v lVithint-hevatt are housings 17 and 18,

each of which has a bracket 19-therci n in which a pipe 20 is rotatabl said pipe extending 'througi the walls of mounted, the if the casings 17 and "18, a liquid tight joint-I.

being provided where the said pipe extends through the said Walls; Intermediate the end of the pipe 20 a coil 21 has its ends in communication with the'said pipe, thesaid coil being wound around theipipe, in order that it will act as an agitator when the pipe is rotated and in order also that liquidmay circulate through it for thepurpose-of heat-.

ing or cooling the cream contained in the;

vat according to whether the cream 'in-the vat is to be. heated or cooled. Thecoil 21 is connected to the pipe20 by a'hollow web A the opening of which flares-from the coil to the pipe.

Within the housing 17 the pipe 20 hasa ear wheel 22 which'meshes with a gear wheel 23 on the shaft 24, the said shaft having a sprocket wheel 25 near itsupper'end suitably driven from the shaft 26, thelatter shaft being journaled" in appropriate bearings and having power communicated to it through the gearing 27. While I have" specified the method of driving the shaft 24' through the sprocket wheel 25and thegea'r v ing, it is tobe understood that the exact manner of communicating motion to the shaft 24: is an immaterial detail of construction', and I do not, therefore, wish to be'lim- .may have a hose or other conduit 30 con- .The arm 34 is nected to' it leading into the chamber where it is supplied with the heating or cooling liquid as the case' may be.

The housing 17 has an annular flange 31 on its exterior and the housing 1-8 has an annular flange 32 on its exterior. The housing 17 has a collar 33 which engages the an- 1 by a collar 38 having an'arm 39 with a hollow boss 40 which is threaded to receive the screw 11. It will be observed, therefore, that by the rotation of the shaft 14:, the

shafts 8 and'9 are rotated and consequently the screws andll are turned to raise the collar which have their arms supported by the screws and the said collars in turn comw municate motipn'to the housing, elevating or lowering them accordin' to the direction of rotation of the'said sha ts. I

By reason of the provision'of the mechanism just described,it is apparent that an operator may elevate orlower the housing,

consequently lowering or elevating the heat interchanging coil 21 and as means are'provided for rotating the said heat interchangingmeans, it follows that-the. cream. contained inthe yet will be simultaneously agitated and acted upon by the agent within the coils.i The op'erator'ma'y, therefore, control the-temperature of the cream within the vat while atthe same time agitating it for thepurpose of uniformly ripening the said cream. As shown Fig. 2, a packing I box 41 is interposedbetween the pipe and 1 the pipe 29, thus permitting the rotation of the pipe 20 independently of the pipes 28 and 29. Y

The manner of cooling the contents of the chamber 5 or of heating the said contents is immaterial-although it is common in practice tosupply ice to the said'chamberfor the purpose of'cooling .the said liquid.

and .to heat the chamberin any appropriate -way when the temperature of the liquid within thevat is to raised.

'1 claim .jLfIn a cream. ripening machine, a vat, housings vertiea'lly movable therein and means formoving them, a. pipe rotatably mountedv in the housing, andmeans for rotating the'pipe.

'2. Ina cream ripening machine, a vat,

housings vertically movable thereln and means for moving them,la' pipe rotatably mounted inthe housing,-means-for rotating the pipe,'and a coilin' 'communication with the pipe, the said coil surrounding the pipe. I

3. In a cream ripening machine, a vat, housings inthe vat, means for moving the housings-vertically, a piperotatable 1n the vat and supported by. the housings, means for rotating the pipe, and means for supplying liquid .to the p1pe.-

In testimony whereof, I afiix iny signature in the'presence of two witnesses.
